To all 'io/tom t may conce/1w Be it known that I, MBnnsoN MUC Uiinnr, a citizen of the United States, residing at Monroe, in the countyof Green and State of lWisconsin, have invented certain new and useful Improvements in Molds, of which. the following is a specification, reference being had to the accompanying drawings.

This invention relates to molds, and has for its object to provide a mold capable of molding tubular devices such as cisterns, cesspool necks, etc.

It is also an object of the invention to provide a mold of this character wherein the walls of the mold can be readily removed from the product, after the material has set, without danger of injuring` the product.

It is a further object of the invention to provide a mold of this character including an inner and outer wall, said walls cooperating to provide an endless chamber for the reception of the material used in the formation of the product. j

It is still a further object of the invention to provide a mold of this character particularly adapted for molding endless or tubular objects and wherein each wall of the mold is separable to permit removal of the walls of the mold from the product independently of each other.

With these and other objects in view, the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which :u

Figure 1 is a top plan view of a mold constructed in accordance with an embodiment of the invention;

Figure 2 is a side elevation of the mold;

Figure 3 is a section taken on the line 3-3 of Figure 1 and showing the product in the mold;

Figure 4 is a detailed plan of the fastening means of the inner wall, and

Figure 5 is a perspective view of the product of the mold with a cover applied.

Referring to the drawings7 5 designates a base member which may be made of any suitable material, said base member having two annular series of openings for the reception of bracing pins 6 and`7, the purpose of which will be hereinafter described.

In connection with the base 5, an outerv annular wall member 8 is provided. This wall member consists of a sheet of r'naterial7 MOLD.

Serial No. 600,278.

preferably metal, split as at 9 to provide 'end portions 10 and 11. The end portion 10 is provided with cleats 12 which project a considerable distance beyond said end port1on. The end portion 11, similar to the end portion 10, is provided with cleats 13 which project beyond said end toward the cleats 12. The projecting end portions of the cleats 13 are intended to be disposed in wardly of the cleats 12 and to engage the adjacent side edges of the cleats 12 so as to properly position the end faces of the end portions 10 and 11 and provide an. endless annular wall when the mold is set up for use.

In order to reinforce the outer wall, the reinforcing bands 14 and 15 are provided. each band having ears 16 formed at their ends and provided with registering openings for the reception of a bolt 17. By this means it is impossible for the weight of the material to cause the wall to separate.

In connection with the outer wall 8, an inner annular wall 18 is provided, the inner wall being split as at 19 to provide end portions 2O and 21, the confronting end faces of said end portions being adapted to engage each other to provide an endless wall. In order that the end portions 20 and 21 of the wall 18 may be securely locked without requiring bands or like fastening' means to be passed around the outer edge of the wall, there is provided novel fastening means. This fastening means comprises a keeper 22, tion 23 extended at right angles to the keeper and provided with a recess 24, the end portion 23 extending inwardly of the annular wall 18. The keeper is secured to the end portion 21 of the wall adjacent the edge of said end portion. Carried by the end portion 2O inwardly of the edge of said end portion is a supporting member 25 having its end portion 26 offset and provided with an opening. A lever 27 has its end portion 28 pivoted to the offset portion 26. The portion 29 of said lever is also offset substan tially in parallel relation to theoifset portion 26 and again offset as at 30 to provide a latch member.

To operate the fastener, the portion 29 adjacent the latch 30 is engaged with the side of the end portion 23, to urge the end faces of the wall into engagement with each other. One of these latches is provided at the top of the wall and one at the bottom, 'the entire latch. meehanism extending lnsaid keeper having its end por.

Wardly eilt-lie wall so as to eliminate j iro'jee tions in the chamber ,of the mold.

In the use of the device, the outer annular Wall 8 is placed upon the hase 5 and the lower hand l5 applied as Well as the upper hand le, so as to urge the edges of the split portion 9 into engagement with each other. The pins 6 are then placed in the opening of the hase to properly brace the outer Wall. The inner Wall is smaller in dian'ieter than the outer Wall and is 'intended to heplaced within the outer wall in annular spaced relation t seid outer Wall to provide a incid chamber fil, said chamber `being annular. Alfter the inner `ivall has heen plated in position, the fastening; means is actuated to connect the ends oi the wall. The pins T are Vv then placedV in the hase so as to brace the Well from the inner lace thereof. Concrete. cement or lilze material may then he placed in the chamber 3l to torni the device A.

This mold particularly edapted for the production of .cist erns, cesspool necks and like devices. .ln Figure 5 is shown a perspective `vieiv ol? u. cesspool iieclr .und cover, the cover being' inade oil" the suine materiel as the neel;4 and reinforced vith rods, one Aoft said rods providing` :i lnindleg the handle heing; disposed centrally oit the cover. From the oregoing it will he readily seen that this invention provides a novel orm of mold particularly adapted for use in the iFornra-tion of cesspool necks, cisterne, or in `fact7 any device requiringv a tubular hody` member. ln addition to this, regardless of the tact that the product is annuler, there no danger `ot the product being damaged when the mold is beingdisassembled. This releasing and removing;

is accomplished hv the hands 14 and l5, and separating; the edges of the outer annular wall so as to permit `the sinne to he readily removed. The inner #all may also he easily removed hy actuating` the fl'asteni-,i-,ipg ineens to separate the ends and to permit said ends to he overlapped to decrease the diameter ot the Wall the wall to he readily reand thus permit All oithese moved from the lnein'her A. features are possessed hy a device composed neefjes/i of only ai small number olf simple parts which may he easily assembled leind `disassembled. Y

1lWhat is claimed iisgl. A mold comprising a hase, a tubular youter lWall disposed on the hase, e tubular inner Well disposed on the hase inwardly oit the outer Wall, eachy of said Walls being split at one point, cleats carried by the edges of the split portion of the outer Well, the cleets of each edge engaging the Vopposite edge tor holding` said confronting Aedges o said split portion in engagement ,iv-ith each other to provide en even surface, reiniorc'mphands carried hy the upper and lower portions of the outer Wall, said hands .being` adapted to engage the outer cleats ol: the wall, means 'for securing .said hands to said Wall, `and fastening means carried hy the inner wall,

said igastening means projecting from the inner surface olfl the inner Well, seid inner Wall heilig disposed in ennuar spaced rela tion to the `outer-will to provide an .endless mold chamber.
